Create a short list of standard cases with rounded dimensions on Window > Standard Cases and Pallets > Standard Metric Unit Cases - External Dimensions.
Open a new document window starting from primary package on New Data Sheet > Start from Primary Package.
Then the Load Multiple Packages window through the Tools menu.
Enter the package dimensions and the amount that will be shipped. In this case, the dimensions are 220x180x48, the amount is 25 items and 0.63 kg. Click on the Add Package button to add the package to the list. When finish, click on Done.
What you have now is the primary package input window in which you have stored the packages to be use for filling boxes. You will notice that the primary package area is greyed out, select Fill Standard Cases from the Standard Cases menu.
Select Recalculate from the Tools menu to see the results. The product will not be shipped on such an inefficient pallet, the user just need to know which boxes to use and how to pack the shipment he must deliver.
To calculate the rest of the shipments you must set the amount to 30, 45 or 60. For that go to File > Change Data and repeat the steps 3 to 6.
